=__**Lesson 1: The Basics of Exponents**__=

By now, you already know how to add, subtract, multiply, and divide. You also probably realize that multiplication is just a shorthand way of expressing an addition problem. Rather than say 4+4+4 (which is 4 three times), we write 4x3 (which is 4 times 3). It's the same thing.

Exponential expressions are similar. Just as multiplication is repeated addition, powers are repeated multiplication. Rather than write 4x4x4x4x4, we write 4 5. It's a shorthand way of saying the same thing. Below is a presentation on the basics of exponents (there's much more to learn). After you've mastered that, we'll go over our rules for the order of operations. But that's for another lesson.
